ronildoq Posted February 22, 2019 Author Posted February 22, 2019 SMT at Procella's amazing ATMOS 24.4.10 HT set up at the ISE show in Amsterdam last week ! 40 custom cardboard Wings togheter with 40 Crystal ceiling diffusors was installed. Amazing stuff really. Last night I rewatched the book of Eli, the gun shooting demo clips, superb decay , suddenly I have a “Phantom Wide” channel in my system now, feels very immersive in a bubble now. The widths are much “ enhanced” and “depth” from the sound of bullets is unbelievable and they decay off nicely... feels really awesome I gotta a shock a few times and thought something dropped off from my from surrounds Sent from my iPhone using Tapatalk

I notice when the "Adjust RTA Levels" is checked -- the measurement is pretty close to what I see on the iPhone DecibelX app. I think the "Adjust RTA Levels" need to be checked for noise floor measurement. What do you think? Use this setting when you want to adjust subwoofers using the RTA on the fly. This method is good when determining the best combinations between two subwoofers. Play a pink pn (periodic noise) while adjusting the distance on avr/phase controls and look at the big screen for its interaction and adjust the distance/phase until you find the perfect blend. There is also a DB meter above that shows you the sum of both subs SPL as you adjust the distance/phase Sent from my iPhone using Tapatalk
wizardofoz Posted February 27, 2019 Posted February 27, 2019 Why such secrecy for supplier info on a door? Surely others will also want to know without having to PM individually :D

wizardofoz Posted February 27, 2019 Posted February 27, 2019 Im sure they would be happy for the business lead...just post their website free to all to use :D
ronildoq Posted February 28, 2019 Author Posted February 28, 2019 I don’t think they have a website even, one Uncle Wenson, but he is very experienced, had got good understanding of acoustics as well https://www.sgpbusiness.com/company/Jnw-Reno-Building-Services-Pte-Ltd Office is at Bukit Batok Price also very reasonable compared to many out there Can try approach him.

ronildoq Posted April 14, 2019 Author Posted April 14, 2019 Some reading for SMT Diffusors http://diffusor.com/PDF/170515_Resolution_Mag.PDF And some feedback from musicians around the world, taken from SMT page. It’s really that good... World famous Tuulikki Bartosik found its long-awaited reference Forest acoustics in a small game changing Wing bubble in Stockholm !! "For the first time in my life, I heard the harmonics in my instrument and by hearing them I could bring them into my music making. When I play on my instrument I always sit and try to shape the sound. But when I sit in the wing room, everything falls into place. I connect with my instrument and my inner self when my soul is in contact with what is around. Now I completely relax and stop looking for my sound, because it is so clear that I now have access to the full capacity of my self and my instrument, because I now hear just about every detail, just as if I were in the forest. Except in this studio, this level of detail I have only experienced in my forest in southern Estonia” Tuulikki.Bartosik More info SMT:s Forest acoustic concept http://diffusor.com/PDF/170515_Resolution_Mag.PDF Sent from my iPhone using Tapatalk

ronildoq Posted February 3, 2020 Author Posted February 3, 2020 Here is a very good video on why this $200k system didn’t “satisfy” its owner [embed=425,349] [/embed] That’s why experience is important and a good acoustician will tell u that In the advice above, he advocates front back diffusion and sides first reflection with absorption, then two specific diffusor exactly beside MLP , near the surround speakers At the end of my journey, I noticed these really brought up the system up to the next level. If u r planning your new HT with acoustics, I’d suggest this 1. Measure your subwoofers before u even move in, use room simulation and find that best MLP, sub placement is the most difficult 2. Once u have that, first thing target all corners or trihedral sections, place good bass trap panels, (dihedral Mount) 3. Ideally your MLP is 2/3 from back wall. Go full diffusion behind MLP ( this is very critical, it brought up a whole lot of difference). If the seats are near, then no choice, absorption 4. If u go with diffusion, SMTs are TOP class, no joke, use all SMTs, don’t mix rojak. It’s not ex, but the shipping is and cumbersome no local dealers 5. On the side walls, diffusion again, single piece as recommended. Just beside MLP. An effective one like the smt really brings the system to another level. The other day I was listening to stereo, and I was shocked to hear the sound extends all the way to the left right of MLP , thanks mainly to the SMTs, they are solid 6. Front wall I went with bass traps, there were pros and cons here. Previously with SMTs at front wall, the width was better. But bass was less controlled. And now the reverse , bass better control, but lesser width. 7. Ceiling, hybrid approach. With bass traps above with air GAP to ceiling, and beneath surface of it diffusion. Why I chose this? Firstly, not to disturb neighbours upstairs. Secondly for Atmos, we need diffusion. With the BAD panels at ceiling, the sound stage extends all the way up (height). There are two clear layers, ground and heights, Very syok ! 8. On the first reflection points for mains, absorption, this is placed at the angle of incidence There u go, that’s the very basic for HT. Take this basic approach, and I’ll assure u the system will be up at least by 50-60-% improvement , best if u can get acoustic Consultants, if cash not an issue

ronildoq Posted February 10, 2020 Author Posted February 10, 2020 Some of it does look like the SMTs, especially the veritune V4 [emoji1787][emoji1787] Are those PRDs from SMT? Haven’t seen such design

ronildoq Posted February 11, 2020 Author Posted February 11, 2020 I see. I suspect too many diffusion stuff at his place. Can see from the pics For front wall, I think bass traps absorption is good, same for first reflection points at the left and right speaker area Ceiling would be good if he went for the golden horn, because I believe redirection or sound re-direction overhead sounds nicer For surrounds at 90degrees definitely go with diffusion, same behind MLP. Definitely diffusion, the whole back wall disappears with diffusion at the back I think he should have used a better product like the SMT Wings, that’s calculated, rather than the PRDs that redistributes sound and reflection So from the video,I’ve also learnt one thing, other than buying the product, type of product and placement will be key factors how the system sounds

QRD , PRD or MLSD all are diffuser using math to calculated and design; Wings on the other hand is using small “partition” to transit and delay the sound , SMT get the idea from the sound travel through the trees in the forest in Sweden , I think might have some mathematics involve but so far he did not announce the mathematics theory behind it unlike QRD , PRD or MLSD. https://usir.salford.ac.uk/id/eprint/26633/1/11332557.pdf I am pretty sure the room layout was design by Matt the SMT boss himself......or at least his Distributer in US because it is full of SMT style, especially the adjustable Helmholtz cum diffuser at side wall (those are not to redirect sound like the youtube guy said) Matt like to incorporate Helmholtz absorbing design into diffuser. My point is not to say which design is good or bad, but looking at the photo and listening to online comments sometime really difficult to imagine how the sound of the room will be.... we don’t know the reason of why the room owner don’t like the sound , who Know, maybe his preference is old nasty JBL type of sound but he choose “wrong” Rockport speaker , or maybe he get use to room with heavy bass but the room bass is too clean for him? Let sit down as watch how the new design become...
ronildoq Posted February 12, 2020 Author Posted February 12, 2020 Very true, a lot of valid points u have laid out there!

Yea that’s my personal finding so far. I prefer diffusion at side walls 90 degrees, they provide the width, very good, whilst diffusion behind MLP, provides the depth. The single biggest benefit I noticed is the one behind MLP. Treating that area is quite significant As for the first reflection off side walls from main speakers, I concur with the YouTube video guy, absorption preferred
ronildoq Posted May 15, 2020 Author Posted May 15, 2020 Some pictures to share , BTW, still love the SMT wings, the best diffusers ... a pity we don’t have a local distributor Sent from my iPhone using Tapatalk Pro
ronildoq Posted July 24, 2020 Author Posted July 24, 2020 Some new design coming up by SMT, if you haven’t yet got your diffusors,u might want to wait for this. The SMTs are worth waiting for. Apparently it’s 110mm and 250mm in depth, this is now pending patent before being released to the mass market The new diffusors looks promising as can be seen from the impulse response on “temporal diffusion” . It can be seen like a pink noise burst, with 7ms delay with Low end equal even absorption . This is like 1.5x the spaciousness effect from the current S Wing model that I am currently using This will be exceptionally good, in small living space environments like our HDB. It tricks our brain to expose different time masking effects, the results of which is clear details , vocals and extremely good timbre. Something all audiophiles love These are spatial and temporal diffusors . They redirect reflections in space and time. They are extremely good and retains the energy in the room , removing all the negative effects of comb filtering etc. We can see above the extension of the reflected broadbanded time delay vs the previous version of V wings as below at 4.8ms ( the longer the delays and evenness, the more spaciousness the feeling is) Wait for it !

ronildoq Posted August 31, 2020 Author Posted August 31, 2020 Recently we came across another good company dealing with acoustic panels, his work, skills are immaculate, very neat, nice I’ve upgraded to have 3 pieces of 60x60x18cm bass trap right beneath the SMT wings If you ever want to do up your room acoustics, placing the bass trap panels beneath the diffusor is ideal. This should be at the bottom at the height at 60-80cm. The acoustic diffusors panels are ideal at 60-80cm above ground, like this This method for placement is highly effective, and very significant especially behind MLP The panels are specially built to specs , to provide for maximum air flow resistivity So we went with a front area coverage of Foil reinforced Kraft paper, 60kg density of rockwool, followed by a 6mm ply to act as a pressure membrane FRKP Back of it with 6mm ply Completed panels They are very effective and it’s placed ideally beneath the SMT wings Still no news so far on the new SMT products, following closely... they are extremely good, the best diffusor !
